METHOD OF INCREASING THE ENERGY OF A FLUID-MOTOR IN MOTOR-DRIVEN TORIEDOES.

No Drawing.

To all whom it may concern:

Be it known that I, MICHEL BRUNIQUEL, engineer, residing at 43 Rue de la Federation, Paris, in the Republic of France, have invented certain new and useful Improvements in Methods of Increasing the Energy of a Fluid-Motor in Motor-Driven Torpedoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In motor driven torpedoes operated by means of compressed air, a superheater is employed for increasing the energy available for the propulsion, and consequently increasing the speed and power of these engines. This superheater is inserted in the pipe which connects the air reservoir with the motor, and in it is ignited a preferably liquid combustible, such as petrol, spirit or the like, conveyed automatically under pressure. The energy produced by this combustion is added to that of the compressed air. This increase'of energy is limited by considerations of the strength of the constructional materials at high temperatures. Also in certain of these superheaters in order further to increase the available energy without reaching-too high temperatures, a portion of the heat evolved by the combustion of the liquid combustible or the like is employedfor vaporizing water conveyed also under pressure into the superheater.

This invention has for its object a process which enables the quantity of gaseous fluid I released in the combustion chamber'to be increased in a certain proportion according to requirements, and which consequently allows the energy of the fluid motor to be notably increased. This process consists in injecting into the superheater, oxygenated water (hydrogen peroxid) of suitable strength (to be determmed for each particular case), which being vaporized will pro- Speciflcation of Letters Patent.

duce oxygen and steam, while releasing a certain quantity of heat. The oxygen insures a more complete combustion of the combustible, and. if the strength is suitably selected will .enable a larger quantity of the latter to be burnt. For this reason the energy available in the motor will be increased in a proportion dependent on the strength of the hydrogen peroxid employed, more particularly by employinga peroxid, which is sufliciently rich in oxygen, air might be dispensed with and the mixture of peroxid and combustible burnt in a combustion motor. Further as the peroxid only solidifies at low temperatures, it has a great advantage over the ordinary water at present employed for torpedoes which are required to work in winter or in cold countries.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. The process of increasing the energy supplied to a motor driven by compressed fluid which consists in subjecting such fluid while on its Way to the motor, to the heat of a suitable fuel in combustion while injecting hydrogen peroxid into the sphere of combustion.

2. The process of increasing the energy supplied to a motor driven by compressed fluid which consists in burning a'suitable fuel in such fluid while on its way to the motor, and simultaneously mingling hydrogen peroxid with the same, whereby the temperature is suitably controlled while a suitable proportion of oxygen is supplied to prevent resultant impairment of combustion.

In testimony whereof, I have afiixedmy signature, in presence of two witnesses.
